FIELD OF THE INVENTION

The invention relates to compounds that bind the glucagon-like peptide 1(GLP-1) receptor, methods of their synthesis, and methods of theirtherapeutic and/or prophylactic use. The present invention is directedto compounds adapted to act as modulators of the GLP-1 receptor, andpotentiators of incretin peptides, such as GLP-1(7-36) and GLP-1(9-36),and oxyntomodulin, as well as peptide-based therapies such as exenatideand liraglutide.

BACKGROUND

Glucagon-like peptide 1 receptor (GLP-1R) belongs to Family B1 of theseven-transmembrane G protein-coupled receptors, and its natural agonistligand is the peptide hormone glucagon-like peptide-1 (GLP-1). GLP-1 isa peptide hormone arising by its alternative enzymatic cleavage fromproglucagon, the prohormone precursor for GLP-1, which is highlyexpressed in enteroendocrine cells of the intestine, the alpha cells ofthe endocrine pancreas (islets of Langerhans), and the brain (Kieffer T.J. and Habener, J. F. Endocrin. Rev. 20:876-913 (1999); Drucker, D. J.,Endocrinology 142:521-7 (2001); Hoist, J. J., Diabetes Metab. Res. Rev.18:430-41 (2002)). The initial actions of GLP-1 observed were on theinsulin-producing cells of the islets, where it stimulatesglucose-dependent insulin secretion. Subsequently, multiple additionalantidiabetogenic actions of GLP-1 were discovered including thestimulation of the growth and inhibition of the apoptosis of pancreaticbeta cells (Drucker, D. J., Endocrinology 144:5145-8 (2003); Holz, G. G.and Chepurny O. G., Curr. Med. Chem. 10:2471-83 (2003); List, J. F. andHabener, J. F., Am. J. Physiol. Endocrinol. Metab. 286:E875-81 (2004)).

Like GLP-1 Oxyntomodulin is also generated from L-cell derivedproglucagon by alternative proteolysis. Oxyntomodulin is identical toglucagon plus an additional 8 amino acid carboxyterminal extension(Bataille D., et al, Peptides 2 Suppl s:41-4 (1981)). Oxyntomodulin is adual agonist of both GLP-1 receptor and glucagon receptor. Oxyntomodulininduces glucose dependent insulin secretion from pancreatic βcells(Maida, A., et al, Endocrinology 149:5670-8 (2008), and in vivo,oxyntomodulin modulates food intake (Dakin, C. L. et al, Endocrinology142:4244-50 (2001)) and is significantly anorectic (Baggio, L. L. et al,Gastroenterology 127:46-58 (2004)).

On activation, GLP-1 receptors couple to the α-subunit of G protein,with subsequent activation of adenylate cyclase and increase of cAMPlevels, thereby potentiating glucose-stimulated insulin secretion.Therefore, GLP-1 is an attractive therapeutic target to lower bloodglucose and preserve the β-cells of the pancreas of diabetic patients.Glucagon has been used for decades in medical practice within diabetesand several glucagon-like peptides are being developed for varioustherapeutic indications. GLP-1 analogs and derivatives are beingdeveloped for the treatment for patients suffering from diabetes.

As used in the specification and the appended claims, the singular forms“a,” “an” and “the” include plural referents unless the context clearlydictates otherwise.

As used herein, “individual” (as in the subject of the treatment) meansboth mammals and non-mammals. Mammals include, for example, humans;non-human primates, e.g., apes and monkeys; cattle; horses; sheep; andgoats. Non-mammals include, for example, fish and birds.

A “receptor”, as is well known in the art, is a biomolecular entityusually comprising a protein that specifically binds a structural classof ligands or a single native ligand in a living organism, the bindingof which causes the receptor to transduce the binding signal intoanother kind of biological action, such as signaling a cell that abinding event has occurred, which causes the cell to alter its functionin some manner. An example of transduction is receptor binding of aligand causing alteration of the activity of a “G-protein” in thecytoplasm of a living cell. Any molecule, naturally occurring or not,that binds to a receptor and activates it for signal transduction, isreferred to as an “agonist” or “activator.” Any molecule, naturallyoccurring or not, that binds to a receptor, but does not cause signaltransduction to occur, and which can block the binding of an agonist andits consequent signal transduction, is referred to as an “antagonist.”Certain molecules bind to receptors at locations other than the bindingsites of their natural ligands and such allosteric binding molecules maypotentiate, activate or agonize the receptor and may enhance the effectof a natural ligand or a co-administered ligand.

A “GLP-1 compound” or “GLP-1 agonist” or “GLP-1 activator” or “GLP-1inhibitor” or “GLP-1 antagonist” or “GLP-1 potentiator” or “GLP-1modulator” as the terms are used herein refer to compounds that interactin some way with the GLP-1 receptor. They can be agonists, potentiators,or activators, or they can be antagonists or inhibitors. A “GLP-1compound” of the invention can be selective for action of the GLP-1receptor family.

“Substantially” as the term is used herein means completely or almostcompletely; for example, a composition that is “substantially free” of acomponent either has none of the component or contains such a traceamount that any relevant functional property of the composition isunaffected by the presence of the trace amount, or a compound is“substantially pure” is there are only negligible traces of impuritiespresent.

Substantially enantiomerically or diastereomerically pure means a levelof enantiomeric or diastereomeric enrichment of one enantiomer withrespect to the other enantiomer or diastereomer of at least about 80%,and more preferably in excess of 80%, 85%, 90%, 95%, 98%, 99%, 99.5% or99.9%.

“Treating” or “treatment” within the meaning herein refers to analleviation of symptoms associated with a disorder or disease, orinhibition of further progression or worsening of those symptoms, orprevention or prophylaxis of the disease or disorder.

The expression “effective amount”, when used to describe use of acompound of the invention in providing therapy to a patient sufferingfrom a disorder or malcondition mediated by GLP-1 refers to the amountof a compound of the invention that is effective to bind to as anagonist or as an antagonist a GLP-1 receptor in the individual'stissues, wherein the GLP-1 is implicated in the disorder, wherein suchbinding occurs to an extent sufficient to produce a beneficialtherapeutic effect on the patient. Similarly, as used herein, an“effective amount” or a “therapeutically effective amount” of a compoundof the invention refers to an amount of the compound that alleviates, inwhole or in part, symptoms associated with the disorder or condition, orhalts or slows further progression or worsening of those symptoms, orprevents or provides prophylaxis for the disorder or condition. Inparticular, a “therapeutically effective amount” refers to an amounteffective, at dosages and for periods of time necessary, to achieve thedesired therapeutic result by acting as an agonist of GLP-1 activity. Atherapeutically effective amount is also one in which any toxic ordetrimental effects of compounds of the invention are outweighed by thetherapeutically beneficial effects. For example, in the context oftreating a malcondition mediated by activation of a GLP-1 receptor, atherapeutically effective amount of a GLP-1 receptor agonist of theinvention is an amount sufficient to control the malcondition, tomitigate the progress of the malcondition, or to relieve the symptoms ofthe malcondition. Examples of malconditions that can be so treatedinclude, but not limited to, type II diabetes, as well as NAFLD andNASH.

All chiral, diastereomeric, racemic forms of a structure are intended,unless a particular stereochemistry or isomeric form is specificallyindicated. Compounds used in the present invention can include enrichedor resolved optical isomers at any or all asymmetric atoms as areapparent from the depictions, at any degree of enrichment. Both racemicand diastereomeric mixtures, as well as the individual optical isomerscan be synthesized so as to be substantially free of their enantiomericor diastereomeric partners, and these are all within the scope ofcertain embodiments of the invention.

The isomers resulting from the presence of a chiral center comprise apair of non-superimposable isomers that are called “enantiomers.” Singleenantiomers of a pure compound are optically active, i.e., they arecapable of rotating the plane of plane polarized light. Singleenantiomers are designated according to the Cahn-Ingold-Prelog system.Once the priority ranking of the four groups is determined, the moleculeis oriented so that the lowest ranking group is pointed away from theviewer. Then, if the descending rank order of the other groups proceedsclockwise, the molecule is designated (R) and if the descending rank ofthe other groups proceeds counterclockwise, the molecule is designated(S). In the example in Scheme 14, the Cahn-Ingold-Prelog ranking isA>B>C>D. The lowest ranking atom, D is oriented away from the viewer.

“Isolated optical isomer” means a compound which has been substantiallypurified from the corresponding optical isomer(s) of the same formula.Preferably, the isolated isomer is at least about 80%, and preferably atleast 80% or even at least 85% pure. In other embodiments, the isolatedisomer is at least 90% pure or at least 98% pure, or at least about 99%pure, by weight.

Enantiomers are sometimes called optical isomers because a pureenantiomer rotates plane-polarized light in a particular direction. Ifthe light rotates clockwise, then that enantiomer is labeled “(+)” or“d” for dextrorotatory, its counterpart will rotate the lightcounterclockwise and is labeled “(−)” or “1” for levorotatory.

The terms “racemate” and “racemic mixture” are frequently usedinterchangeably. A racemate is an equal mixture of two enantiomers. Aracemate is labeled “(±)” because it is not optically active (i.e., willnot rotate plane-polarized light in either direction since itsconstituent enantiomers cancel each other out).

It is understood that due to chemical properties (i.e., resonancelending some double bond character to the C—N bond) of restrictedrotation about the amide bond linkage (as illustrated below) it ispossible to observe separate rotamer species and even, under somecircumstances, to isolate such species, example shown below. It isfurther understood that certain structural elements, including stericbulk or substituents on the amide nitrogen, may enhance the stability ofa rotamer to the extent that a compound may be isolated as, and existindefinitely, as a single stable rotamer. The present inventiontherefore includes any possible stable rotamers of compounds of theinvention which are biologically active in the treatment of type Idiabetes, type II diabetes, gestational diabetes, obesity, excessiveappetite, insufficient satiety, metabolic disorder, non-alcoholic fattyliver disease and/or non-alcoholic steatohepatitis.

The preferred compounds of the present invention have a particularspatial arrangement of substituents on the aromatic rings, which arerelated to the structure activity relationship demonstrated by thecompound class. Often such substitution arrangement is denoted by anumbering system; however, numbering systems are often not consistentbetween different ring systems. In six-membered aromatic systems, thespatial arrangements are specified by the common nomenclature “para” for1,4-substitution, “meta” for 1,3-substitution and “ortho” for1,2-substitution as shown below.

All structures encompassed within a claim are “chemically feasible”, bywhich is meant that the structure depicted by any combination orsubcombination of optional substituents meant to be recited by the claimis physically capable of existence with at least some stability as canbe determined by the laws of structural chemistry and byexperimentation. Structures that are not chemically feasible are notwithin a claimed set of compounds. Further, isotopes of the atomsdepicted (such as deuterium and tritium in the case of hydrogen) areencompassed within the scope of this invention. For example, it shouldbe understood that depiction herein of compounds having one or morehydrogen atoms is intended to encompass compounds having such hydrogenatoms replaced with deuterium (or tritium) at one or more locations ofsuch compounds. Such “deuterated compounds”, whether partial (i.e, lessthan all the hydrogen atoms replaced with deuterium) or complete (i.e.,all the hydrogen atoms replaced with deuterium) is within the scope ofthe compounds of this invention.

In general, “substituted” refers to an organic group as defined hereinin which one or more bonds to a hydrogen atom contained therein arereplaced by one or more bonds to a non-hydrogen atom such as, but notlimited to, a halogen (i.e., F, Cl, Br, and I); an oxygen atom in groupssuch as hydroxyl groups, alkoxy groups, aryloxy groups, aralkyloxygroups, oxo(carbonyl) groups, carboxyl groups including carboxylicacids, carboxylates, and carboyxlate esters; a sulfur atom in groupssuch as thiol groups, alkyl and aryl sulfide groups, sulfoxide groups,sulfone groups, sulfonyl groups, and sulfonamide groups; a nitrogen atomin groups such as amines, hydroxylamines, nitriles, nitro groups,N-oxides, hydrazides, azides, and enamines; and other heteroatoms invarious other groups. Non-limiting examples of substituents that can bebonded to a substituted carbon (or other) atom include F, Cl, Br, I,OR′, OC(O)N(R′)₂, CN, CF₃, OCF₃, R′, O, S, C(O), S(O), methylenedioxy,ethylenedioxy, N(R′)₂, SR′, SOR′, SO₂R′, SO₂N(R′)₂, SO₃R′, C(O)R′,C(O)C(O)R′, C(O)CH₂C(O)R′, C(S)R′, C(O)OR′, OC(O)R′, C(O)N(R′)₂,OC(O)N(R′)₂, C(S)N(R′)₂, (CH₂)₀₋₂NHC(O)R′, (CH₂)₀₋₂N(R′)N(R′)₂,N(R′)N(R′)C(O)R′, N(R′)N(R′)C(O)OR′, N(R′)N(R′)CON(R′)₂, N(R′)SO₂R′,N(R′)SO₂N(R′)₂, N(R′)C(O)OR′, N(R′)C(O)R′, N(R′)C(S)R′, N(R′)C(O)N(R′)₂,N(R′)C(S)N(R′)₂, N(COR′)COR′ N(OR′)R′, C(═NH)N(R′)₂, C(O)N(OR′)R′, orC(═NOR′)R′ wherein R′ can be hydrogen or a carbon-based moiety, andwherein the carbon-based moiety can itself be further substituted.

Substituted alkyl, alkenyl, alkynyl, cycloalkyl, and cycloalkenyl groupsas well as other substituted groups also include groups in which one ormore bonds to a hydrogen atom are replaced by one or more bonds,including double or triple bonds, to a carbon atom, or to a heteroatomsuch as, but not limited to, oxygen in carbonyl (oxo), carboxyl, ester,amide, imide, urethane, and urea groups; and nitrogen in imines,hydroxyimines, oximes, hydrazones, amidines, guanidines, and nitriles.

Substituted ring groups include substituted aryl, heterocyclyl andheteroaryl groups. Substituted ring groups can be substituted by one ormore substituents at any available ring position. In some embodiments,two substituents on a substituted ring group may taken together with thering to which they are attached to form a ring, such that the two ringsare fused together. For example, benzodioxolyl is a fused ring systemformed by two substituents taken together on a phenyl group.

Such substituted ring groups also include rings and fused ring systemsin which a bond to a hydrogen atom is replaced with a bond to a carbonatom. Therefore, substituted aryl, heterocyclyl and heteroaryl groupscan also be substituted with alkyl, alkenyl, cycloalkyl, aryl,heteroaryl, and alkynyl groups as defined herein, which can themselvesbe further substituted.

The linking groups (e.g., L₁ and L₂) of Formula I-R or I-S are partialstructures which may be represented by a formula, say, for example,—N(R₁)—C(O)—, which is read from left-to-right. Accordingly, thenitrogen atom of the —N(R₁)—C(O)— linker will be attached to theproximal end of the structure of Formula I-R or I-S, and the carbonylcarbon atom of the —N(R₁)—C(O)— linker will be attached to the distalend of the structure of Formula I-R or I-S.

The term “heteroatoms” as used herein refers to non-carbon andnon-hydrogen atoms, capable of forming covalent bonds with carbon, andis not otherwise limited. Typical heteroatoms are N, O, and S. Whensulfur (S) is referred to, it is understood that the sulfur can be inany of the oxidation states in which it is found, thus includingsulfoxides (R—S(O)—R′) and sulfones (R—S(O)₂—R′), unless the oxidationstate is specified; thus, the term “sulfone” encompasses only thesulfone form of sulfur; the term “sulfide” encompasses only the sulfide(R—S—R′) form of sulfur. When the phrases such as “heteroatoms selectedfrom the group consisting of O, NH, NR′ and S,” or “[variable] is O, S .. . ” are used, they are understood to encompass all of the sulfide,sulfoxide and sulfone oxidation states of sulfur.

A fully saturated ring has no double bonds therein, and iscarbocyclic or heterocyclic depending on the presence of heteroatomswithin the meaning herein.

When two “R” groups are said to be joined together or taken together toform a ring, it is meant that together with the carbon atom or anon-carbon atom (e.g., nitrogen atom), to which they are bonded, theymay form a ring system. In general, they are bonded to one another toform a 3- to 7-membered ring, or a 5- to 7-membered ring.

The carbonyl carbon atom is also bonded to another carbon atom,which can be part of an alkyl, aryl, aralkyl cycloalkyl,cycloalkylalkyl, heterocyclyl, heterocyclylalkyl, heteroaryl,heteroarylalkyl group or the like. In the special case wherein thecarbonyl carbon atom is bonded to a hydrogen, the group is a “formyl”group, an acyl group as the term is defined herein. An acyl group caninclude 0 to about 12-20 additional carbon atoms bonded to the carbonylgroup. An acyl group can include double or triple bonds within themeaning herein. An acryloyl group is an example of an acyl group. Anacyl group can also include heteroatoms within the meaning here.

The terms “comprising,” “including,” “having,” “composed of,” areopen-ended terms as used herein, and do not preclude the existence ofadditional elements or components. In a claim element, use of the forms“comprising,” “including,” “having,” or “composed of” means thatwhatever element is comprised, had, included, or composes is notnecessarily the only element encompassed by the subject of the clausethat contains that word.

A “salt” as is well known in the art includes an organic compound suchas a carboxylic acid, a sulfonic acid, or an amine, in ionic form, incombination with a counterion. For example, acids in their anionic formcan form salts with cations such as metal cations, for example sodium,potassium, and the like; with ammonium salts such as NH₄ ⁺ or thecations of various amines, including tetraalkyl ammonium salts such astetramethylammonium, or other cations such as trimethylsulfonium, andthe like. A “pharmaceutically acceptable” or “pharmacologicallyacceptable” salt is a salt formed from an ion that has been approved forhuman consumption and is generally non-toxic, such as a chloride salt ora sodium salt. A “zwitterion” is an internal salt such as can be formedin a molecule that has at least two ionizable groups, one forming ananion and the other a cation, which serve to balance each other. Forexample, amino acids such as glycine can exist in a zwitterionic form. A“zwitterion” is a salt within the meaning herein. The compounds of thepresent invention may take the form of salts. The term “salts” embracesaddition salts of free acids or free bases which are compounds of theinvention. Salts can be “pharmaceutically-acceptable salts.” The term“pharmaceutically-acceptable salt” refers to salts which possesstoxicity profiles within a range that affords utility in pharmaceuticalapplications. Pharmaceutically unacceptable salts may nonethelesspossess properties such as high crystallinity, which have utility in thepractice of the present invention, such as for example utility inprocess of synthesis, purification or formulation of compounds of theinvention.

Suitable pharmaceutically-acceptable acid addition salts may be preparedfrom an inorganic acid or from an organic acid. Examples of inorganicacids include hydrochloric, hydrobromic, hydriodic, nitric, carbonic,sulfuric, and phosphoric acids. Appropriate organic acids may beselected from aliphatic, cycloaliphatic, aromatic, araliphatic,heterocyclic, carboxylic and sulfonic classes of organic acids, examplesof which include formic acetic, propionic, succinic, glycolic, gluconic,lactic, malic, tartaric, citric, ascorbic, glucuronic, maleic, fumaric,pynivic, aspartic, glutamic, benzoic, anthranilic, 4-hydroxybenzoic,phenylacetic, mandelic, embonic (pamoic), methanesulfonic,ethanesulfonic, benzenesulfonic, panthothenic, trifluoromethanesulfonic,2-hydroxyethanesulfonic, p-toluenesulfonic, sulfanilic,cyclohexylaminosulfonic, stearic, alginic, β-hydroxybutyric, salicylic,galactaric and galacturonic acid. Examples of pharmaceuticallyunacceptable acid addition salts include, for example, perchlorates andtetrafluoroborates.

Suitable pharmaceutically acceptable base addition salts of compounds ofthe invention include, for example, metallic salts including alkalimetal, alkaline earth metal and transition metal salts such as, forexample, calcium, magnesium, potassium, sodium and zinc salts.Pharmaceutically acceptable base addition salts also include organicsalts made from basic amines such as, for example,N,N′-dibenzylethylenediamine, chloroprocaine, choline, diethanolamine,ethylenediamine, meglumine (N-methylglucamine) and procaine. Examples ofpharmaceutically unacceptable base addition salts include lithium saltsand cyanate salts. Although pharmaceutically unacceptable salts are notgenerally useful as medicaments, such salts may be useful, for exampleas intermediates in the synthesis of Formula I compounds, for example intheir purification by recrystallization. All of these salts may beprepared by conventional means from the corresponding compound accordingto Formula I by reacting, for example, the appropriate acid or base withthe compound according to Formula I. The term “pharmaceuticallyacceptable salts” refers to nontoxic inorganic or organic acid and/orbase addition salts, see, for example, Lit et al., Salt Selection forBasic Drugs (1986), Int J. Pharm., 33, 201-217, incorporated byreference herein.

A “hydrate” is a compound that exists in a composition with watermolecules. The composition can include water in stoichiometricquantities, such as a monohydrate or a dihydrate, or can include waterin random amounts. As the term is used herein a “hydrate” refers to asolid form, i.e., a compound in water solution, while it may behydrated, is not a hydrate as the term is used herein.

A “solvate” is a similar composition except that a solvent other thatwater replaces the water. For example, methanol or ethanol can form an“alcoholate”, which can again be stoichiometric or non-stoichiometric.As the term is used herein a “solvate” refers to a solid form, i.e., acompound in solution in a solvent, while it may be solvated, is not asolvate as the term is used herein.

A “prodrug” as is well known in the art is a substance that can beadministered to a patient where the substance is converted in vivo bythe action of biochemicals within the patient's body, such as enzymes,to the active pharmaceutical ingredient. Examples of prodrugs includeesters of carboxylic acid groups, which can be hydrolyzed by endogenousesterases as are found in the bloodstream of humans and other mammals.

“Isotopes” are well known in the art and refer to atoms with the samenumber of protons but different number of neutrons. For example, carbon12, the most common form of carbon, has six protons and six neutrons,whereas carbon 14 has six protons and eight neutrons.

In addition, where features or aspects of the invention are described interms of Markush groups, those skilled in the art will recognize thatthe invention is also thereby described in terms of any individualmember or subgroup of members of the Markush group. For example, if X isdescribed as selected from the group consisting of bromine, chlorine,and iodine, claims for X being bromine and claims for X being bromineand chlorine are fully described. Moreover, where features or aspects ofthe invention are described in terms of Markush groups, those skilled inthe art will recognize that the invention is also thereby described interms of any combination of individual members or subgroups of membersof Markush groups. Thus, for example, if X is described as selected fromthe group consisting of bromine, chlorine, and iodine, and Y isdescribed as selected from the group consisting of methyl, ethyl, andpropyl, claims for X being bromine and Y being methyl are fullydescribed.

GLP-1 PAM Shift cAMP Assay: Dose Response of Peptide Ligand in Presenceof Fixed Concentration of Compound.

A GLP-1R expressing CRB-bla CHO-K1 cell line was purchased fromInvitrogen. Cells were seeded into 384-well white flat bottom plates at5000 cells/well/20 μL growth media (DMEM-High glucose, 10% dialyzed FBS,0.1 mM NEAA, 25 mM Hepes, 100 U/mL penicillin/100 μg/mL streptomycin, 5μg/mL Blasticidin, 600 μg/mL Hygromycin) and incubated for 18 h at 37°C. in 5% CO₂. Growth medium was replaced with 12 μL assay buffer (HanksBalanced Salt solution, 10 mM Hepes, 0.1% BSA, pH 7.4). A 5× peptidedose response curve (12-point) was generated in assay buffer containing1.5 mM IBMX, 12.5% DMSO, and 50 μM compound. Peptide ligand wasGLP-1(9-36). The 5× peptide dose response plus compound mix was added (3μL) and cells were incubated for 30 min at 37° C. Direct detection ofcAMP was carried out using DiscoveRx HitHunter cAMP kit according tomanufacturer's instructions and luminescence was read using a SpectraMaxM5 plate reader. Luminescence was analyzed by non-linear regression todetermine the EC₅₀ and Emax. A GLP-1(7-36) dose response was included todetermine maximum efficacy.

EC₂₀GLP-1 (9-36) PAM cAMP Assay: Dose Response of Compound in thePresence of Fixed Concentration of GLP-1

GLP-1R CRE-bla CHO-K1 cells cultured in growth medium (DMEM-Highglucose, 10% dialyzed FBS, 0.1 mM NEAA, 25 mM Hepes, 100 U/mLpenicillin/100 μg/mL streptomycin, 5 μg/mL Blasticidin, 600 μg/mLHygromycin) were trypsinized and plated in suspension into 384 wellwhite flat bottom plates at 5000 cells/well in 12 μL assay buffer (HanksBalanced Salt solution, 10 mM hepes, 0.1% BSA, pH 7.4). A 5× compounddose response curve (12-point) was generated in assay buffer containing1.5 mM IBMX, 4% DMSO. GLP-1(9-36) was diluted to 4.2 μM in assay buffercontaining 1.5 mM IMBX and 4% DMSO. The 5× compound dose response wasadded (3 μL), followed by 0.5 μL of GLP-1(9-36) and cells were incubatedfor 30 min at 37° C. Direct detection of cAMP was carried out usingDiscoveRx HitHunter cAMP kit according to manufacturer's instructionsand luminescence was read using a SpectraMax M5 plate reader.Luminescence was converted to total cAMP using a cAMP standard curve anddata was analyzed by non-linear regression to determine the EC₅₀ andEmax.

In Vivo Procedures

The Oral Glucose Tolerance Test in C57B1/6 Mice.

Fasted C57BL/6 female mice are 8-10 weeks of age. Sitagliptin, compound,or vehicle is dosed at least 1 hr prior to the oGTT. Mice receive abolus of glucose (3 g/kg) by oral gavage (time 0). Blood samples arecollected at frequent time intervals from the tail tip for glucosemeasurement (BD glucometer; Becton-Dickinson, Lincoln Park, N.J.).

The Oral Glucose Tolerance Test in Ob/Ob Mice

Fasted ob/ob female mice are 7-10 weeks of age. Sitagliptin, compound,or vehicle is dosed at least 1 hr prior to the oGTT. Mice receive abolus of glucose (0.2 g/kg) by oral gavage (time 0). Blood samples arecollected at frequent time intervals from the tail tip for glucosemeasurement (BD glucometer; Becton-Dickinson, Lincoln Park, N.J.).

The Oral Glucose Tolerance Test in fa/fa Rats.

The use of the compounds of this invention to lower glucose can beevaluated in rats using the protocol described by Pederson et. al.(Diabetes, Vol. 47, August 1998, 1253-1258). After an overnight fast,lean or obese animals are administered oral glucose by syringe andfeeding tube (1 g/kg) as a 40% solution (wt/vol). Compound is dissolvedand administered along with the glucose. In control experiments, vehicleis administered along with oral glucose. Blood samples are collectedfrom the tail veins of conscious unrestrained rats into heparinizedcapillary tubes at 0 and 5, 10, 20, 30, and 60 min after glucoseadministration. Blood samples are centrifuged at 4° C., and plasma isstored at −20° C. until analysis for glucose and insulin measurement.Glucose levels are measured using the glucose oxidase procedure (Beckmanglucose analyzer; Fullerton, Calif.).
